## Summary

Powitt Solar is a Chinese manufacturer founded in 2007 and headquartered in Changzhou, Jiangsu province. The company claims roughly 1 GW of annual production capacity and operates automated lines across facilities in Wuxi and Changzhou, with satellite offices in Australia and Sri Lanka. Powitt markets its panels under a "Tier 1 technology" label, but no independent confirmation of a BloombergNEF bankability listing was found in current sources - a meaningful distinction for project finance. Q-Cells, now branded Qcells and operating as a subsidiary of South Korea's Hanwha Group (a Fortune Global 500 conglomerate), is a confirmed BloombergNEF Top Tier bankable supplier and was named to the S&P Global 2025 Tier 1 Cleantech list. With combined module capacity exceeding 11 GW per year globally and a fully integrated U.S. manufacturing plant under completion in Cartersville, Georgia, Qcells commands a far stronger institutional footprint than Powitt.

On the product side, Powitt's catalog is centered on N-type bifacial panels spanning a wide wattage range, aimed primarily at cost-sensitive buyers in export markets who need flexible, high-output modules for ground-mounted or commercial rooftop installations. Qcells addresses a broader spectrum: the Q.PEAK DUO line uses PERC technology for budget-conscious residential buyers, while the newer Q.TRON series deploys N-type TOPCon cells with efficiency up to around 22.5% and annual degradation rates confirmed at approximately 0.4%, targeting premium residential and light commercial rooftops. Qcells also pursues utility-scale and emerging perovskite-silicon tandem research.

For a typical buyer in 2025, Qcells is the more defensible choice - its bankability is independently verified, its U.S. domestic manufacturing reduces tariff exposure, and its warranty track record is well-documented by independent reviewers. Powitt can be a rational pick for off-grid, DIY, or price-driven projects where third-party bankability is not a financing requirement, but buyers should weigh the limited independent review coverage against more established alternatives.
